Is it possible to access draw (Open GL) api from native code?

Hello!

Is it possible to access draw api from native code? For example I need to make some calculations and draw some primitives to not to frame buffer but to texture, and maybe apply some custom shaders to it. 

Is it possible with Corona?

Custom shader effects are in private beta. If interested send me a note: walter at coronalabs dot com, and I can get you added.
